4. Catalyst: Yttrium oxide is also used as a catalyst or catalyst carrier, and is widely used in petrochemical and automobile exhaust treatment. Its high surface area and stable chemical properties make it excellent in catalytic reactions.

Yttrium oxide upstream and downstream raw materials

1. Upstream raw materials: The production of yttrium oxide mainly depends on rare earth minerals such as monazite and xenotime. After a series of processes such as crushing, leaching, precipitation and calcination, high purity yttrium oxide can be obtained from these minerals. The development and supply of rare earth mineral resources has a direct impact on the production of yttrium oxide.

2. Downstream Products: Yttrium oxide is a key raw material for many high-tech products, including optical glass, lasers, ceramic materials and electronic components. With the continuous advancement of technology in these fields and the growth of market demand, the application range and market prospects of yttrium oxide are also expanding.

Yttrium oxide storage method

Yttrium oxide has strong chemical stability, but the following points should be paid attention to during storage:

1. Moisture-proof: Although yttrium oxide is insoluble in water, a humid environment may cause it to be hygroscopic. Therefore, yttrium oxide should be stored in a dry environment to avoid contact with moisture in the air.

2. Sealed storage: The use of sealed containers to store yttrium oxide can effectively prevent its moisture absorption and pollution, and maintain its purity and stability.

3. Prevention of pollution: The environment in which yttrium oxide is stored should be kept clean and avoid contact with other chemicals to prevent impurity contamination.

4. Temperature control: Although yttrium oxide has good thermal stability, the storage temperature should not be too high to avoid performance degradation caused by long-term high-temperature storage.
